CIA Triad Write Up
The CIA triad is essential part to understand the 3 major components of
cybersecurity. The use of the triad in cybersecurity. It highlights what all cybersecurity
professionals fundamentally do in their jobs.
Confidentially
The C in the CIA triad means confidentiality. Information has different security priorities
depending on what the info is about. Most of the time in the business world, information
has some sort of security boundary whether its password protected or behind a locked
door protected. The more sensitive information is only to be known by the superiors of a
business.
Integrity
The I in the CIA triad means Integrity. Information should have safeguards and
redundancies to ensured that information in the system is not lost, inappropriately
changed, whether deliberately or accidentally.
Availability
The A in CIA triad means Availability. Information must always be accessible to the
superiors in a company. It must be protected by a security boundary, if its super easy to get
into on our end its probably easy to get into by a bad guy.

Authentication vs Authorization
Authentication is the process of identifying a user on a platform. Example: logging into
your Midas account and having send a push notification on your phone to verify your
identity.
Authorization is the permissions that you are given after logging into a device or system.
Example: would be like using child account on Netflix, you will be only allowed to watch kid
rated content.
The difference between them is that authentication always comes before authorization.
To play a game on a computer you must enter your password then you can access the
game.
